Where, exactly, does learning happen in the brain? Out today in @nature.com, we identify a synaptic locus of birdsong learning and show that the circuit can be tuned to make birds learn faster - but at a cost. Read on👇 #neuroskyence 🧪 #prattle 💬 #bioacoustics Shareable link: rdcu.be/fiyrS

New paper: We show that especially female mice benefit from moderate early life adversity under stressful situations in adulthood. This pro-resilient effect requires the psychiatric risk factor FKBP51, which turns out to be also required for adaptive stress responses. www.nature.com/articles/s41...

Temperature-related deaths in European cities could increase by up to 50% by the end of the century in the absence of climate change-mitigation policies, totalling up to 2.3 million additional deaths, suggests a paper published in Nature Medicine. go.nature.com/4glnYzU 🧪
This is figure 3, which shows city-level net changes in temperature-related excess death rates for each warming level under scenario SSP3-7.0 and no adaption to heat.

Deconstructing the neural circuit underlying social hierarchy in mice
Xin et al. find that in the dorsomedial prefrontal cortex (dmPFC), layer 2/3 neurons projecting to the anterior basolateral amygdala promote losing, whereas layer 5 neurons projecting to the dorsal raphe nucleus and periaqueductal gray promote winning. Moreover, the lose-related pathway inhibits the win-related pathways through local GABAergic interneurons.
